• Network Access Point (NAP)
• system management and access to the
Internet and system wide services
• Backhaul
• Infrastructure components
• antennae, cable, mounts

Links
More NAP
• Supports 7 CAPS
• Half height indoor free-standing 19”
equipment cabinet
• Equipment includes:
• High speed CISCO router
• 100BaseT CISCO Ethernet switch
• UPS
• NMS Workstation
CISCO Router
• Directional gateway between the LMS2000
network and the Internet
• SNMP Managed
• GUI configured
CISCO Ethernet Switch
• Gateway that moves data between the
NAP and the CAP
• Enables connecting up to seven CAPs to
one NAP Ethernet switch via 10/100 BaseT
compatible Backhaul.
• Serves as the system connection point for
the NMS workstation.
• SNMP managed
• GUI configured
Bandwidth Management
• EUMs transmit data at the max rate which creates
competition for bandwidth
• Prevents inconsistent data transmission and
overloading the system
• Provides for the allocation of data traffic rates to and
from the EUM
• Provided by the router for smaller systems, dedicated
Bandwidth Network Manager (BWM) in large systems
• NMS application allocates service levels to each EUM
• Allows differentiated service levels generating
additional revenue
• SNMP managed
• GUI configured
NAP UPS
• An alarm will indicate power shutdown which
allows operator a minimum of 10 minutes to
perform a graceful shutdown.
• Continuous protection from power surges,
spikes, or sags on the main power lines.
• SNMP managed
• GUI configured
NMS Workstation
• Personal computer equipped with a
printer, keyboard, mouse, backup tape
drive, and a uninterruptible power supply
(UPS) with APS PowerChute PLUS
software for monitoring system power
levels.
• The NMS Workstation contains the
software for managing the LMS2000
system.
NMS Software
•
•
•
•
Microsoft Windows NT 4.0 Workstation (with Service Pack 6a)
WaveRider LMS Network Management System
Microsoft SQL Server
Vircom VOP RADIUS
– server controls the logon and authentication access for the EUMs.
Each EUM has a coded ID/password combination that RADIUS will
use to recognize the modem.
• Castlerock SNMPc Server
• Tardis Timeserver
– provides time synchronization between the Internet and the CAP
and NAP hardware
• APS PowerChute PLUS
• Veritas Backup Exec with Microsoft SQL Agent
• Mirrored Hard Drive Disc System RAID 2
The CAP
• Provides the path for the NMS to the EUMs
• Provides the central radio access point for EUMs
• Provides a path for Internet data to travel between the EUM
and the NAP for routing to the Internet.
• Up to 3 active channel units - hot swappable
• Extra channel unit and switch matrix for redundancy
• UPS
• 10/100 BaseT connection for backhaul Link to
.

•
3 CAP channel units (CCU)
Cisco Ethernet switch
Uninterruptible power supply (UPS)
Additional channel unit and RF switch matrix for
channel unit redundancy (option)
• Additional hardware supporting the CAP RF
subsystem, including antennae, antennae
mount, lightning arrestors, cabling, and
connectors
• Backhaul equipment not contained in the CAP
cabinet
CCU
• Based on proprietary WaveRider wireless and IP
technology
• Wired-to-wireless conversion
• 11 Mbps wireless data rate
• IP router function
• Up to 30 EUM’s
• FCC/IC approved
• SNMP managed
• GUI configured
CAP CISCO Ethernet Switch
• Gateway that moves data between the CCUs and the
backhaul interface
• Collects data from multiple CCUs and directs all the
data into a single stream (aggregates) then sends the
streamed data to the external backhaul
• In the NAP-CAP direction the Ethernet switch collects
data from the backhaul and fans it out to multiple
CCUs
• GUI configured
CAP UPS
• An alarm will indicate power shutdown which
allows operator a minimum of 10 minutes to
perform a graceful shutdown.
• Continuous protection from power surges,
spikes, or sags on the main power lines.
• SNMP managed
• GUI configured
Backhaul
• Determined by the configured size of the
CAP, the available backhaul infrastructure
and spectrum in the service area, and the
distance between the CAP and the NAP
• Consult WaveRider System Engineer for
determining
• Should be SNMP managed
• Fast as the slowest link
EUM
• Based on WaveRider proprietary
wireless and IP technology
• IP router function
• FCC/IC approved
• SNMP managed
• GUI configured
Redundancy Features
Need
• System reliability is measured by the
availability of the system to the subscribers.
• Down time is a critical factor in maintaining
customer satisfaction and a solid revenue
flow.
Design Features
• Industry leading Cisco routers & switches to
ensure long term reliability and industry
compatibility
• Key system elements (NAP, NMS, CAP)

ISM band integrated components and
WaveRider modem technology
Design Features
• Policy-based bandwidth management
ensures disciplined control of all access to
the valuable system bandwidth resources
• Back-up CAP channel unit, CCU, constantly
monitors active channel units and
automatically replaces a defective channel
Centralized Network
